NX 9000v mac address table weirdness?

I'm working on a 9000v, default config, VLAN 1 all ports.

I have 2 docker hosts on e1/1 and 1/2 respectively and can ping between the ports no problem.

show mac address on the 9000v:

switch# sho mac address-table interface e1/1 Legend: * - primary entry, G - Gateway MAC, (R) - Routed MAC, O - Overlay MAC age - seconds since last seen,+ - primary entry using vPC Peer-Link, (T) - True, (F) - False, C - ControlPlane MAC VLAN MAC Address Type age Secure NTFY Ports ---------+-----------------+--------+---------+------+----+------------------ switch# sho mac address-table interface e1/2 Legend: * - primary entry, G - Gateway MAC, (R) - Routed MAC, O - Overlay MAC age - seconds since last seen,+ - primary entry using vPC Peer-Link, (T) - True, (F) - False, C - ControlPlane MAC VLAN MAC Address Type age Secure NTFY Ports ---------+-----------------+--------+---------+------+----+------------------ switch# sho mac address-table vlan 1 Legend: * - primary entry, G - Gateway MAC, (R) - Routed MAC, O - Overlay MAC age - seconds since last seen,+ - primary entry using vPC Peer-Link, (T) - True, (F) - False, C - ControlPlane MAC VLAN MAC Address Type age Secure NTFY Ports ---------+-----------------+--------+---------+------+----+------------------ 

It's like it's just forwarding everything and not learning at all?

I am missing something stupid, or is this normal behavior for the 9000v in GNS3?

Thanks.
